Molecular tagging measurement technique is an advanced non-intrusive visualization
approach which uses the molecules as the tagging and tracking materials. This technique …

Single-point and two-point focused laser differential interferometry (FLDI) are used to
explore the structure of a turbulent boundary layer in a Mach 2.6 in-draft wind tunnel's test …

This manuscript describes the wide variety of optical measurement techniques for
characterizing the flow in hypersonic wind tunnels. The introduction briefly describes …

In this work, we study the effect of the compression-corner angle on the streamwise turbulent
kinetic energy (sTKE) and structure in Mach 2.8 flow. Krypton tagging velocimetry (KTV) is …

The supersonic wind tunnel facility SBR-50 at the University of Notre Dame was built in 2015
for experimental research related to shock wave (SW) interactions with obstacles and …

A self-aligned focusing schlieren (SAFS) system combines the field of view of a conventional
schlieren system with the defocus blur of a focusing schlieren system away from the object …

HIGH-SPEED wind tunnels typically rely on pressure and/or temperature measurement and
nozzle-flow calculations to determine the freestream conditions. This practice can require a …

Femtosecond laser electronic excitation tagging (FLEET) is a nonintrusive optical diagnostic
technique that has been demonstrated to provide direct measurement of velocity and other …

Acetone tagging velocimetry (ATV) with nominally 1% mole fraction acetone seeding was
conducted in a shock-tunnel-generated hypersonic turbulent boundary layer over a hollow …
